Apart from the suggestions given, try a faster film if your current one regularly requires 1/30 or even 1/60th and the negs are fuzzy. Even with D3200 grain won't be a problem unless the prints are very large. Better a little grain than fuzziness.
Yes, I intend to do that. I mostly shoot Acros and Reala, ISO100 film. Now I have some Delta 3200, which is a HUGE step up there, so I should get a better idea what the camera can do at better shutter speeds.
